I once was behind a very posh lady in a big flash white Mercedes Benz behind a big old cattle truck.
We were going up the hill in town out front of the police station and courthouse.
As the truck stopped at the intersection at the top of the hill and all of the residue of excreta and liquid flowed forward with the momentum, then gravity did it's thing.
Naturally, of whom was most likely a well to do city Merc owner, she got as far up the butt of the cattle truck in front as she could, as is the way in the big city.
Ignorant of any likely consequences and not well schooled in the ways of cattle in cattle trucks.

It was like a wave of S&%# that hit that Merc.
All over the bonnet, windscreen - got the lot.
It was way too funny.

I don't know what she did, maybe borrowed someone's hose in a front yard?
The owners wouldn't be too agreeable to such a thing.

I was only a young fella at the time but it also taught me a very valuable lesson.
I now give cattle trucks and the like a VERY wide berth!!!!
